English as a Second Language/Question

I walked into Government House, a large holdover from the Stalinist era, past an enormous statue of Genghis Khan, the 13th century Mongolian warrior whose empire spanned a larger land mass than any other in history.

Best,

Hossein

AnswerHi Hossein,

past here means passing by

"larger land mass than any other in history" means an area of land larger than any other such area in history. In other words, Genghis Khan's empire was the largest empire ever in history at that time.
